What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study aims to find out how common airway closure is in adults who are on a breathing machine (ventilator) in the intensive care unit. Researchers will check 75 patients within 48 to 72 hours after they are put on a ventilator, using a special breathing test to detect closure. The goal is to describe the prevalence and identify any patient traits linked to it.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand and manage airway closure in ventilated ICU patients, potentially improving care.
What could go wrong
This is a small, observational study with only 75 participants, so findings may not apply to all ICU patients. It does not test a treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.
